Step 1
configure term
isdn switch-type basic-net3
dialer-list 1 protocol ip permit
step 2
interface bri 0
ip address negotiated
encapsulation ppp
dialer string 169
dialer load-threshold 255 outbound
dialer-group 1
ppp authentication chap callin
ppp chap hostname 169
ppp chap password 169
Step 3
interface Ethernet0
ip address 192.168.1.1 255.255.255.0
ip nat inside
interface BRI0
ip nat outside
Step 4
ip nat inside source list 1 interface BRI0 overload
ip route 0.0.0.0 0.0.0.0 BRI0
access-list 1 permit 192.168.1.0 0.0.0.255
FW:有几个不懂还请帮着解释一下
isdn switch-type basic-net3 (这是中国交换机的型号?)
dialer load-threshold 255 outbound (呵呵~~~~~看不懂)
ip nat inside(为什么在以太网上用NAT,不是用在串口上映射私有地址号吗?)
interface BRI0
ip nat outside(什么意思?)
ip nat inside source list 1 interface BRI0 overload (呵呵~~~~老大,我看不懂这个了)
sdn switch-type basic-net3 (这是中国交换机的型号)
dialer load-threshold 255 outbound (采用链路)
ip nat inside(私有地址在公网上不许用(建议:看网络基础))
interface BRI0
ip nat outside(作为NAT的外部端口)
ip nat inside source list 1 interface BRI0 overload (做PAT)
dialer load-threshold 255 outbound 是百分百的带宽利用率
FW:关于dialer load-threshold
根据需要增加呼叫提高带宽
在轮换组中一个接口的值达到设定的参数时,后面的呼叫从轮换组中的接口拨出。说白了就是设置一个负载值让路由器在需要的时候拨第2个B通道
